+
+Nostr Coinjoin Discovery
+---------------------------------------
+
+`draft` `author:kukks`
+
+## Introduction
+The BTCPay Server Coinjoin plugin offers a coinjoin endpoint discovery feature over Nostr for a coordinator runner and a coinjoin client to eaasily discover each other.
+
+
+## Specification
+This NIP introduces a NIP16 replaceable kind `15750`, with the following tags:
+* `type`: Signals what kind of coinjoin protocol is being provided. In the case of the BTCPay Server coinjoin plugin, this is `wabisabi`. Other possible options could be `whirlpool`, `bip78`, `joinmarket`, etc.
+* `network`: Signals the bitcoin network the coinjoin protocol is operating on. Always lowercase, can be `mainnet`,`testnet`, `signet`, `regtest`.
+* `endpoint`: A URI of where a user may connect to to interact with the coinjoin.
+
+The content of the event COULD be used to describe the coinjoin endpoint, such as fees, round parameters, etc.
+
+As a client, you SHOULD check that the event was created within the last 15 minutes, to ensure that the coinjoin endpoint is still active.
+As a coinjoin endpoint provider, you SHOULD update the event every 15 minutes to signal you are still online.
